Usually vinegar has no effect on the healing of wounds because of its antiseptic effect, but note that it is important to use vinegar made from grain and not from various genetic formulas. And the healing of the wound is mainly directly related to the skin pairing and whether there is infection or not, if there is infection, even after healing, there may be scars. Besides, vinegar can also play the role of promoting the growth of local granulation, and it can also be paired with powder for disinfection, but hospitals usually use hydrogen peroxide, saline, etc. for disinfection, because the use of its disinfection can play the role of thorough wound cleaning, and can remove all kinds of dirty things from the wound, which cannot be done by vinegar. Even for emergency purposes, vinegar should be used as little as possible in general, because it may lead to wound infection. After a wound appears on the body, it needs to be thoroughly cleaned and disinfected, and to reduce the activity of the wound area, and if the situation is more serious, it may also need to take antibiotics, usually in about three days.
